Application filed March 24, 1924. Serial No. 701,308;

This invention relates to rail oilersv and particularly to devices ofthis class designed for use in connection with elevators for lubricatingthe guide rails therefoi; and the object of the inventionv is to providea device of the class describe'dcomposed of a boxshaped container havingan integral projection at one side thereof, means beingprovided formounting a wick or other fibrous body in connection with the projectingend portion of the container and further to the provision of means forsupplying oil, placed in the container, to the wick or other fibrousbody and'thus to the rail to be lubricated; afurther object. being toprovide a gravity feed. oile'r. device'oii the class described and withmeans'for. controlling and regulating the feed of oil therefrom; afurther object being. to provide means for mounting the oiler inconnectionwith the, structure of an elevator and to properly positionthe projecting portion of. the container thereof with reference totherguide rail or rails; and with these and other objects in view, theinvention consists, in a device of the class and forthe purposespecified which is simple in. construction, efiici'ent in use and whichis. constructed as hereinafter described and claimed.

The invention is fully disclosed. in the following specification, of:which the accompanying drawing forms a part, inwhich the separate.parts. oi my improvement are designated. by suitable referencecharacters in each of the views, and in which:

Fig. 1 is a diagrammaticview showing. the topcorner portion of anelevat'or and aguide rail. therefor, showing my improved oiler mountedin position.

Fig. 2 is a section detail view of the o-i ler shown in Fig. 1 and on anenlarged scale.

Fig. 3 is a view similar to Fig. 2' but showing only part of theconstruction and showing' a modification; and,

Fig. 4: is a partial section on of 3..

In Fig. 1 of the drawing I have shown at 5 one top corner portion of anelevator, at done of the guide rails. thereof, and at 7 one of the guideshoes of theelevator- This construction isold and formsno direct part ofmy invention, the same being shown solely for the purposeofvillustrating one use thereof.

In carrying my invention into effect, I provide a box-shaped casing 8which is apthe line M proximately square in form and open at the top andat 9, I have shown a cover for closing the casing 8, said cover beinghinged to the casing as shown at 10 and a spring 11 is mounted on thehinge ofthe cover and cooperates with the cover and the casing fornormally holding the cover in a closed posr. tion. The bottom of thecasing is provided at one side with a projecting member 12 apertured toreceive a bolt 13. In mounting the casing in position, L-shaped bracket14- isemployed, one end of the bracket being mounted in connection;.with the guide shoe 7 as shown at 15, whiletlie'casing 8 is adjustablymounted on the other end portion thereof and retainedinipe bythe bolt13. The other side ofthe casing 8 is provided with a projectingimemb eii16, the outer end portion 17 of which is U- sh-aped in form and as shownvin Figs. 11 and 2 of the drawing, is slightly enlarged or elongated.TheU-shaped formation 1-7 of the members 16 forms a channel 18 in whichthe rail 7 V operates. In the construction shown in Figs. 1 and 2 of thedrawing, the

member 16 is provided with an aperture 19' which opens into ,the casingand into the channel .18, and in practice a 'wick' 20' is mounted in thecasing and passed out through the aperture 19' and flar'ed in thechannel 18 of the memberic. A screw 21 is mounted in the member 16 andis adapter to extend into the aperturllfi) to compress the wick 20 tocontrol the feed of oil through said wick. p v In the use of the deviceas shown in Figs. 1 and 2 of the drawing, it will be understood thattheca-SingS isifilled or part ally filled with oil as indicated at 2'2mFi-gi 2 of the drawing and this oil feeds by gravity through the wick20 and: onto the rail 7. It will be noted that the aperture 19 ispositioned above the bottom of the casing 8 and with this construction,when the level of oil drops below the aperture 19, the lubricant willsiphon through the wick 20. Another. advantage of this; constructionre.- sides in the fact thatany foreign elements in the oil or that maycollect in the. casing 8, will's e'ttle-to the bottom thereof and may becleanedout from time, to time. It will also be understood thatthead'jnstme'nt of the screw 21 by. reason of its" compressing thestrands of the wick 20 which" normally are. gaged to properly fit in,thefap'erture' 19, will control afeed of the oil. to the rail 7 sheet 21 which constitutes the wiper element is retained in position by a sheetmetal plate 27 fashioned to conform with the general shape of the sheet24 and provided with upstanding side flanges 27 which overlap the sidesof the member 16 or the U-shaped portions 17 thereof, the plate 26 beingheld in position by screws 28 passed through the flanges 27 and into themember 16.

1 I also preferably add a number of layers of, leather or similarmaterial 29 to the upper face of the sheet 24 at the outer or free endsthereof'to form within the U-shaped portion 17 of the member 16 and uponthe top of the sheet 24 around the rail, when the device is in use, achamber 30 in which oil may be contained.

In the construction shown in Figs. 3 and 4, the aperture 19 is madesmaller than the aperture 19 shown inFig. 2 of the drawing and the screw21 is made larger or is of a diameter sufficient to close the aperture19 when the screw is seated on a seat 31 as clearly shown in Fig. 3 ofthe drawing. With this construction, a comparatively heavy oil is placedin the casing 8 and the feed of this oil into the chamber 30 isregulated by the screw 21, and it will be understood that no wick isemployed. When the device is first put in use, it is preferred that thescrew be adjust-ed to allow for a complete fiushing of the rails or toprovide a film of oil thereon, after which the screw may be adjusted toprovide the proper feed of oil to keep the rails properly lubricated. Inpractice, it has been found that the use of my oiler, which will containone pint of oil, will supply proper lubrication to the rail or rails ofan elevator for a period of approximately one month after the rails havebeen covered with a film of oil. In the construction shown in Figs. 1and 2 of the drawing, a light oil is preferably used rather than a heavyoil as in the construct-ion shown in Figs. 3 and 4 of the drawing.

It will be understood that in the operation of the oiler as shown inFigs. 3 and .L of the drawing, the leather or fibre sheet 24 together,with the layers 29 will absorb a predetermined amount of the lubricantand will bear on the rail or on the edge and side faces thereof andprovide for the proper lubrication.

sheet 24 and layers of fibre 29 may be replaced by simply removing thescrews 28 and the sheet metal plate employed for retaining the fibremembers in position. The layers 29 of fibre are preferably held inposition by a screw rivet or the like 32, but it will be understood thatthese parts may be made of unitary construction if desired.

It will be understood that while I have shown certain details ofconstruction for carrying my invention into effect, that I am notnecessarily limited in these respects and various changes in andmodifications of the construction herein shown and describe-d may bemade within the scope of the appended claims without departing from thespirit of my invention or sacrificing its advantages.
